What I found
The customer described the same drain problem as on the previous visits: water was left in the dishwasher and the control showed a 5C error. I removed the drain hose to check the drain path and confirmed that water was not moving through it properly.
The drain pump was weak, so it needed replacement rather than another cleaning. For this repair I used Samsung drain pump DD31-00016A.
How I replaced the drain pump
I pulled the dishwasher out of the cabinet and laid it on its side to reach the pump underneath. After disconnecting the wiring and hose connections, I removed the old pump and compared it with the replacement before fitting the new one in the same position.
I reconnected the pump, returned the dishwasher upright and put it back into the cabinet. The sump and the underside were checked while everything was accessible, and the dishwasher was reassembled with the new drain pump in place.
Result
The dishwasher was returned to service with a new DD31-00016A drain pump. The total was $378.70 including tax, with a 6-month warranty on parts and labor.
Part replaced: Samsung dishwasher drain pump DD31-00016A.
